Development of Underwater Wireless Optical Communication

Based on the development of current wireless communication technology, the development of underwater wireless optical communication technology has become a research hot spot. This paper analyzes and summarizes the development of underwater wireless optical communication technology in recent years. At present, the main underwater wireless optical communication technologies contain non-line-of-sight underwater wireless optical communication technology, high-speed underwater wireless optical communication technology, underwater wireless optical communication positioning technology. At the same time there are still some challenges in the development, which include light attenuation and scattering, choice of light sources and detectors, environmental unpredictability, energy consumption and durability, multiple-input and output technology. In this paper, these problems are systematically sorted out and analyzed and outlook the development trend of underwater optical communication technology.
